Sim Racing Hardware Calibration and Linearity
Direct-drive and belt-driven racing wheels (Logitech, Thrustmaster, Fanatec, Moza) rely on linear optical encoders to measure steering input.

Racing Wheel Diagnostic Guidelines
Steering rotation should track smoothly from center (0°) to maximum lock-to-lock angle without deadzone gaps.

How do I test my racing wheel rotation angle and pedals?
Connect your Logitech G29/G923, Thrustmaster T300RS, or Fanatec racing wheel to your computer via USB, turn the wheel left and right, and depress the throttle, brake, and clutch pedals.
Does this tool test 900-degree and 1080-degree rotation angles?
Yes! The visualizer tracks full 900° and 1080° steering lock-to-lock rotation angles in real time.
Can I test load cell brake pedals and H-pattern shifters?
Yes! Analog pedal travel linearity is measured from 0% to 100% full depression.
